using gmail smtp with redmine 2.4.1

It took me forever to get redmine emails working with gmail's smtp server.  After perusing the ruby action mailer website, I set up my redmine configuration.yml to look like this:

# default configuration options for all environments

default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: 'smtp.gmail.com'
      port: 587
      domain: 'pickemupproductions.com'
      user_name: 'redmine@pickemupproductions.com'
      password: '****'
      authentication: 'plain'
      enable_starttls_auto: true

obviously replace password with your actual password.  Also, I'm using google apps with my wife's business domain.  So my username and domain are a bit differnet than what you would use for regular gmail (gmail.com).
